Ultrasonic Movement Detector2
 
Our first ultrasonic movement detector -CPS20 - has been very popular. This is another circuit design which we believe is more sensitive with fewer components. The transducers are mounted on the same PCB as the circuit.(CPS49)

PARKING RADAR
 
NEW - LOWER PRICE!
Price was: $36.26

If you have problems parking then this kit is for you. Using (ultrasonic) sound waves, whose frequency is beyond our range of hearing, we can "measure" a distance. Consequently, a sensor mounted at the back of the car can give an indication of the distance between your car and the car parked behind you or other obstacles (only at the same height as the sensor). When the preset minimum distance is crossed, an audible signal is generated. (K3502)
